ABSTRACT:
This invention relates to the production of black body-generating decoy flares for thrusted applications. Compositions are provided which, when combusted, provide black body radiation. The compositions generally include from about 20% to about 60% metal, such as magnesium or aluminum, from about 5% to about 50% ammonium perchlorate, and from about 8% to about 30% binder. Important to operation of the present invention is the production of graphitized carbon upon combustion of the composition. Accordingly, high carbon content materials are added to the compositions. These materials may include from about 5% to about 30% polyaromatic compounds, such as decacyclene, anthracene, and naphthalene. Other suitable high carbon materials include polyolefins. This invention also discloses methods of using these compositions in thrusted decoy flare applications.
